If you are currently in the middle of a 2-day reduction, consistency is your best tool.
Allow the system (or subject) to process remaining variables without new input.
Why 48 hours? In many technical and biological systems, this is the standard window for "Half-Life" stabilization, where the most significant drop in active levels occurs. What to Expect During the Process
Ensure that external factors (noise, light, heat, or secondary data streams) remain constant so they don't skew the results of your reduction.
